Angle A= 88°
Angle C= 92°
Angle D= 80°
Step-by-step explanation:
Step 1:
From the basic property of Quadrilateral Angle A and Angle C are supplemental( Which means sum of Angle at A and Angle at C is equal to 180 degree)
Step 2:
From the given figure We could relate that
Angle at A = (X-2)°
Angle at C = (X+2)°
Angle at D = (X-10)°
(X-2)° + ( X+2)° = 180°
On simplification
X-2+X+2=180°
2X=180°
and X=180/2
X = 90°
Angle at A= (90-2)° = 88°
Angle at C = (90+2)° = 92°
Angle at D= (90-10)° = 80°
If they proportional, it implies
(x+2)/(x-1) = 8/10
Or 10x +20 = 8x-8
Or 2x = -28 or x = -14
Answer:
Sharing cone holds 9 times more popcorn than a skinny cone.
Step-by-step explanation:
Height of each cone = 9 inches
Radius of the sharing size cone = 3 times radius of the skinny size cone
Let the radius of skinny size cone = r
Then radius of the sharing size cone = 3r
Volume of the sharing size cone =
=
= 27πr²
Volume of the skinny size cone =
=
= 3πr²
Ratio of the volumes =
=
= 9
Therefore, sharing cone holds 9 times more popcorn than a skinny cone.
Answer:
CE = 16
Step-by-step explanation:
<u>From my understanding, the length of cord AB is given. According to the question in the picture attached, you need to find CE.</u>
<em>Triangle ABD and triangle ACE are similar.</em>
<em>Therefore, AB/AC = BD/CE</em>
<em>AB = 6, AC = 8, BD = 12, CE = ?</em>
<em>6/8 = 12/CE</em>
<em>CE = 12x8/6</em>
CE = 16
Therefore, CE is equal to 16.
